Need some Amp help - a little new to properly powering speakers


Hello. 

 I have some polk LSIM707s that I thorough enjoy.

However, at the moment I'm powering them using a Yamaha aventage 3070 receiver which at 150 watts at 8ohms sounds pretty darn good. 

However, since these are rated at 300 watts at 8 Ohms, I assume I will need some more power. I notice at lower volumes a lot of the imaging and clarity disappears. 

I am looking at buying a 300 watt emotiva Amplifier, or a 500 watt emotiva amplifier.

I'm assuming it would be better to purchase the 500 watt per channel emotiva so the speakers won't suck it dry or stress it. 

Am i wrong in this assumption?

Don't waste your money! Going from 150 watts to 300 will only give an increase of a mere 3db more SPL. And that is at the rated limit of the LSIM707's! If you want more clarity at lower volume you need two things: a better speaker and a better amp.I suggest a pair of Quad Electrostatics with Quad amplification! Buying either Emotiva amp is a waste of money! And will not give you the desired clarity. Your Polks and the Yamaha receiver are the limiting factor - typical mid-fi gear!
